Why are some movies and TV shows on PlyTon not given dubbing credits in their descriptions?

Why are some movies and TV shows on PlyTon not given dubbing credits in their descriptions?

1. Sometimes their dubbing credit is not provided to us that we will give them dubbing credit

2. And sometimes we don't find their dubbing credits on open internet who originally dubbed it.

3. Also, we upload everything fan made, so sometimes there is a dubbing, which is a lot of promotional videos like 1xbet, rajbet, etc,, so in that case we can't find their original source, we will give them dubbing credit.

4. And maybe sometimes some of our content is officially dubbed but we can't find it well on open internet that's not our fault so if you are the original author of that content then you can mail us and we will reply you within 4 or 8 days.  I will try to give
